Yeah your right

A number of people have commented that at 5:22, the green population should be expected to beat out the blue population because the blue population suffers from mutations while the green population benefits from them. That effect is real, but it's too small to tip the scales, and I determined it was too complex for the main message of the video. But because some people are interested, I thought I'd lay it out in more detail here. Only 1% of replications by blue creatures produce a green creature (4:52), and another 1% produce orange creatures. This means blue's replication rate is effectively only 98% of the stated value. 9.8% instead of 10%. The green population gets an expected influx of creatures each time step equal to 0.001 (a tenth of a percent) times the number of blue creatures. Here's a desmos graph of the expected changes per time step for blue and green, from the equation in the video. (The green equation has an added term for bonus creatures from blue's mutations.) www.desmos.com/calculator/zhig0dcftg x is the number of blue creatures, and there are sliders for the other parameters if you want to play with them. N is the total, and N-x is the number of green creatures. We can see that when there are 49 or more blue creatures we expect to gain green creatures and lose blue creatures. And if there are 44 or more blues, we expect to lose more blues than greens. But for any number of blues less than this, we expect green to do worse. Green is never expected to outnumber blue. This all assumes no oranges. The fact that the functions add to less than zero for any value reflects the fact that orange is gaining in any of these scenarios. So it's true that in this setup blue suffers losses from mutations to different colors while green benefits, but the magnitude of this effect with the given parameters is too small to make up the difference in base replication chance between green and blue. Additional sims I ran reflect this fact, with green regularly losing, but I chose to animate the first sim I ran because it was a good reminder of how chaotic this system is. I appreciate folks commenting with a critical eye, and this will help me know what to explain more clearly vs what to gloss over in future videos. It was also kind of fun to make the desmos graph. If you like it and want to see more desmos graphs when relevant to other videos, please reply to this comment and tell me so!

He'd have to increase birth rates for almost all creatures (except humans, since they're the problem-) And increase how quickly plants grow (to sustain current human populations, and the soon to be increased animal populations from increasing their birthrates) And since he can't do both of those in one snap (those are seperate actions after all), he'd have to snap twice. Which would kill him more than likely. Also those variables would have to be very precisely changed So.. no, he really couldn't fix it that way. I do agree that decreasing population size was the dumbest possible solution though

Clear and very well animated! For the mathematically inclined, you can read delta as the derivative of N with respect to time, since it is the variation of N. Thus, before adding the crowding term, you get dN/dt = aN, a differential equation whose solution is indeed exponential, N = exp(at) + c. By adding the crowding term, you get dN/dt = aN^2 + bN, and the solution to that differential equation is the logistic function, as stated.

​@@hubierti No, since N actually is a function of t itself (you could write our differential equation as N'(t) = aN(t)) you can't just leave it be when you integrate with respect to t - what we're looking for is a function whose derivative has the original function as a factor. And in fact, the only function f(t) whose derivative f'(t) = some constant * f(t) is the exponential function, and the derivative of e^ax = a*e^ax so the solution must be, like Vincent stated, N(t) = e^at + C since this gives N'(t) = a*e^at = a*N(t).

This reminds me of some of my favorite teachers over the years. You take the time to explain a concept in detail, and show every step of your work, while explaining WHY it's changing and how it's affecting everything else. You also recap things we've gone over before, and recap when you finish a concept. It's wonderful, and honestly, has pushed me to add physics classes to the bio classes i was planning on when I return to school. You've rekindled my love of math, and I applaud you for it. Thank you.

dvir komlosh shoot idk man. I can give you the proof with integration but idk conceptually. But here’s what I think. The reason why tho that dN/dt=N is exponential is that it doesn’t have to move to the right in order to increase faster. Simply increasing makes it increase faster. With dN/dt=t, which results in a quadratic, much slower, you have to increase t in order to increase faster, which lowers the slope.

I'm horrible at maths and science so I don't always understand all the numbers in these videos but all the concepts are really well explained and easy to grasp with a second watch and well-worded google searches. The simulations are also really interesting, easy to follow, and incredibly entertaining, and all of this combines to make your videos some of the best I've seen on KZread- thank you so much!

Oh how my AP Calculus teacher ruined variable specification for me, I know that if I didn't specify N' = Delta when doing a project like this I'd have gotten tossed out a window or something for not defining my variables sufficiently. Other than that petty observation which most people would just be able to figure out if they're not baboon-tier, this video is genuinely an excellently animated, excellently voiced, and phenomenally descriptive example of the fact that there truly are still amazing content creators on this platform.

Thanks for giving me a solid base to my next simulation game.

*Edit* : read response by channel before liking my comment ;) I doubt that green won because of luck in the simulation at 5:19. Blue loses offsprings to mutation (both orange and green) which makes blue worse than the stats suggest. Additionally green has a higher birthrate as blue mutates into green. Although I have to admit that you didn't show the mutation rates, so they could be small enough to be negligible. I think for a better comparison both orange and green could mutate back to blue with the same likelyhood.
